In Q1 2018 we introduced the following changes to our segments structure:

Search and Portal segment (including Geolocation Services) offers a broad range of services in Russia, Belarus and Kazakhstan (and, for periods prior to the imposition of sanctions on Yandex by the government of Ukraine in May 2017, all our services offered in Ukraine), other than those described below. Since Q1 2018 our Search and Portal segment also includes Search and Portal in Turkey and Yandex Launcher, previously reported in Experiments and Yandex.Travel, previously reported in Classifieds.

E-commerce segment includes our Yandex.Market service;

Taxi segment includes our Taxi business (including Yandex.Taxi and Uber in Russia and neighboring countries) and Food Delivery business (including Yandex.EATs and UberEATs);

Classifieds segment includes Auto.ru, Yandex.Realty and Yandex.Jobs;

Media Services segment includes KinoPoisk, Yandex.Music, Yandex.Afisha and Yandex.TV program; Media Services were broken out from Experiments and now constitute a separate business unit;

Experiments segment includes Zen, Yandex.Cloud, Yandex.Health, Yandex.Drive and Yandex Data Factory. Yandex.Cloud and Yandex.Health initiatives previously were a part of our Search and Portal segment. Yandex.Drive is our car sharing service, launched in February 2018.

Eliminations represent the elimination of transactions between the reportable segments, primarily related to advertising.

Prior periods were restated to conform to the current year presentation.

Consolidated Operating Costs and Expenses

Yandex’s operating costs and expenses consist of cost of revenues, product development expenses, sales, general and administrative expenses (SG&A) and depreciation and amortization expenses (D&A). Apart from D&A, each of the above expense categories include personnel-related costs and expenses, relevant office space rental, and related share-based compensation expense. Increases across all cost categories reflect investments in overall growth. In Q1 2018 Yandex's headcount increased by 689 full-time employees. The total number of full-time employees was 8,134 as of March 31, 2018, up by 9% compared with December 31, 2017, and up 25% from March 31, 2017.

Other cost of revenues in Q1 2018 increased 69% compared with Q1 2017, mainly due to an increase of Taxi related outsourced costs and services provided to Taxi corporate clients, for which revenue and related costs are recorded on a gross basis.

Share-based compensation (SBC) expense

SBC expense is included in each of the cost of revenues, product development, and SG&A categories discussed above.

Total SBC expense increased 70% in Q1 2018 compared with Q1 2017. The acceleration of growth rates of our total SBC expense is primarily related to new equity-based grants made in 2017 and early 2018.

Adjusted EBITDA of Taxi was negative RUB 1,712 million in Q1 2018. The increase in Adjusted EBITDA loss was driven by the addition of the acquired Uber business on February 7, 2018, as well as our investments in our Food Delivery business.

Interest income in Q1 2018 was RUB 708 million, flat compared with RUB 709 million in Q1 2017.

Interest expense in Q1 2018 was RUB 221 million, slightly down from RUB 228 million in Q1 2017.

Foreign exchange loss in Q1 2018 was RUB 482 million, compared with a foreign exchange loss of RUB 2,205 million in Q1 2017. This loss reflects the appreciation of the Russian ruble during Q1 2018 from RUB 57.6002 to $1.00 on December 31, 2017, to RUB 57.2649 to $1.00 on March 31, 2018. Yandex's Russian operating subsidiaries' functional currency is the Russian ruble, and therefore changes due to exchange rate fluctuations in the ruble value of these subsidiaries' monetary assets and liabilities that are denominated in other currencies are recognized as foreign exchange gains or losses within the Other loss, net line in the condensed consolidated statements of income. Although the U.S. dollar value of Yandex's U.S. dollar-denominated assets and liabilities was not impacted by these currency fluctuations, they resulted in a downward revaluation of the ruble equivalent of these U.S. dollar-denominated monetary assets and liabilities in Q1 2018.

Income tax expense for Q1 2018 was RUB 1,395 million, up from RUB 782 million in Q1 2017. Our effective tax rate of 43.0% in Q1 2018 was lower than in Q1 2017, primarily due to the effects of certain tax provisions recognized in Q1 2017 related to the results of prior years' tax audits. Adjusted for the similar tax effects, SBC expense and also for deferred tax asset valuation allowances provided on operations of our newly acquired Uber and Foodfox businesses, our effective tax rate for Q1 2018 was 23.5%, compared with 23.8% for Q1 2017.

Adjusted net income margin was 15.1% in Q1 2018, compared with 18.2% in Q1 2017.

As of March 31, 2018, Yandex had cash, cash equivalents and term deposits of RUB 95.2 billion ($1,662.2 million), including cash, cash equivalents and term deposits of Yandex.Taxi in total amount of 26.2 billion ($457.5 million).

Redeemable noncontrolling interests presented in our condensed consolidated balance sheets relate to the equity incentive arrangements we have made available to the senior employees of the Taxi, Classifieds and E-commerce

segments, pursuant to which such persons are eligible to acquire depositary receipts, or receive options to acquire depositary receipts, which entitle them to economic interests in the respective business unit subsidiaries.

The total number of shares issued and outstanding as of March 31, 2018 was 327,690,428 including 289,805,769 Class A shares, 37,884,658 Class B shares, and one Priority share and excluding 2,625,886 Class A shares held in treasury and all Class C shares outstanding solely as a result of the conversion of Class B shares into Class A shares. All such Class C shares will be cancelled.

There were also employee share options outstanding to purchase up to an additional 3.4 million shares, at a weighted average exercise price of $31.37 per share, 0.8 million of which were fully vested; equity-settled share appreciation rights (SARs) for 0.2 million shares, at a weighted average measurement price of $32.18, all of which, excluding SARs for approximately 1,000 shares, were fully vested; and restricted share units (RSUs) covering 13.0 million shares, of which RSUs to acquire 4.3 million shares were fully vested. Equity awards in respect of business unit subsidiaries are described under Redeemable noncontrolling interests above.

Financial outlook

Based on our recent performance, we currently expect our consolidated ruble-based revenue to grow in the range of 28% to 32% for the full year 2018 compared with 2017.

We announced our proposed E-commerce joint venture in December 2017; upon closing of that transaction, which we expect will occur in Q2 2018, we will stop including the full results of that business in our consolidated financial statements. We believe that the impact of the potential deconsolidation of our E-commerce business on our consolidated revenues growth rates will not be material and therefore will not affect our consolidated ruble-based revenue guidance.

Based on the recent performance of Search and Portal, we now expect our Search and Portal ruble-based revenue growth to be in the range of 19% to 21% in the full year 2018 compared with 2017.

This outlook reflects our current view, based on the trends that we see at this time, and may change in light of market and economic developments in the business sectors and jurisdictions in which we operate.

FORWARD-LOOKING STATEMENTS

This press release contains forward-looking statements that involve risks and uncertainties. These include statements regarding our anticipated revenues for full year 2018. Actual results may differ materially from the results predicted or implied by such statements, and our reported results should not be considered as an indication of future performance. The potential risks and uncertainties that could cause actual results to differ from the results predicted or implied by such statements include, among others, macroeconomic and geopolitical developments affecting the Russian economy, competitive pressures, changes in advertising patterns, changes in user preferences, changes in the political, legal and/or regulatory environment, technological developments, and our need to expend capital to accommodate the growth of the business, as well as those risks and uncertainties included under the captions «Risk Factors» and «Operating and Financial Review and Prospects» in our Annual Report on Form 20-F for the year ended December 31, 2017, which is on file with the U.S. Securities and Exchange Commission (SEC) and is available on our investor relations website at http://ir.yandex.com/sec.cfm and on the SEC website at www.sec.gov. All information in this release and in the attachments is as of April 25, 2018, and Yandex undertakes no duty to update this information unless required by law.

USE OF NON-GAAP FINANCIAL MEASURES

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with U.S. GAAP, we present the following non-GAAP financial measures: ex-TAC revenues, adjusted EBITDA, adjusted EBITDA margin, adjusted ex-TAC EBITDA margin, adjusted net income, adjusted net income margin and adjusted ex-TAC net income margin. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with U.S. GAAP. For more information on these non-GAAP financial measures, please see the tables captioned «Reconciliations of non-GAAP financial measures to the nearest comparable U.S. GAAP measures», included following the accompanying financial tables. We define the various non-GAAP financial measures we use as follows:

Adjusted EBITDA means U.S. GAAP net income plus (1) depreciation and amortization, (2) SBC expense, (3) accrual of expense related to the contingent compensation that may be payable to employees in connection with certain business combinations, (4) interest expense, (5) other loss, net, and (6) provision for income taxes, less interest income

Adjusted net income means U.S. GAAP net income plus (1) SBC expense adjusted for the income tax reduction attributable to SBC expense, (2) accrual of expense related to the contingent compensation that may be payable to certain employees in connection with certain business combinations, (3) foreign exchange losses adjusted for reduction in income tax attributable to foreign exchange losses, (4) losses from repurchases of our convertible notes adjusted for the related decrease in income tax and (5) amortization of debt discount related to our convertible debt adjusted for the related reduction in income tax

·

Adjusted net income margin means adjusted net income divided by U.S. GAAP revenues

These non-GAAP financial measures are used by management for evaluating financial performance as well as decision-making. Management believes that these metrics reflect the organic, core operating performance of the company, and therefore are useful to analysts and investors in providing supplemental information that helps them understand, model and forecast the evolution of our operating business.

Although our management uses these non-GAAP financial measures for operational decision-making and considers these financial measures to be useful for analysts and investors, we recognize that there are a number of limitations related to such measures. In particular, it should be noted that several of these measures exclude some recurring costs, particularly share-based compensation. In addition, the components of the costs that we exclude in our calculation of the measures described above may differ from the components that our peer companies exclude when they report their results of operations.

Below we describe why we make particular adjustments to certain U.S. GAAP financial measures:

TAC

We believe that it may be useful for investors and analysts to review certain measures both in accordance with U.S. GAAP and net of the effect of TAC, which we view as comparable to sales commissions but, unlike sales commissions, are not deducted from U.S. GAAP revenues. By presenting revenue, adjusted EBITDA margin and adjusted net income margin net of TAC, we believe that investors and analysts are able to obtain a clearer picture of our business without the impact of the revenues we share with our partners.

SBC

SBC is a significant expense item, and an important part of our compensation and incentive programs. As it is a non-cash charge, however, and highly dependent on our share price at the time of equity award grants, we believe that it is useful for investors and analysts to see certain financial measures excluding the impact of these charges in order to obtain a clearer picture of our operating performance.

Acquisition-related costs

We may incur expenses in connection with acquisitions that are not indicative of our recurring core operating performance. In particular, we are required under U.S. GAAP to accrue as expense the contingent compensation that is payable to certain employees in connection with certain business combinations. We eliminate these acquisition-related expenses from adjusted EBITDA and adjusted net income to provide management and investors a tool for comparing on a period-to-period basis our operating performance in the ordinary course of operations.

Foreign exchange losses

Because we hold significant assets and liabilities in currencies other than our Russian ruble operating currency, and because foreign exchange fluctuations are outside of our operational control, we believe that it is useful to present adjusted net income and related margin measures excluding these effects, in order to provide greater clarity regarding our operating performance.

Amortization of debt discount

We also adjust net income for interest expense representing amortization of the debt discount related to our convertible notes issued in Q4 2013 and Q1 2014.We have eliminated this expense from adjusted net income as it is non-cash in nature and is not indicative of our ongoing operating performance.

Gains and losses from repurchases of convertible debt

Adjusted net income is also adjusted for a loss from the repurchase of $8.0 million in principal of our 1.125% convertible senior notes due 2018 for approximately $7.7 million that we recorded in Q1 2017. We have eliminated this loss from adjusted net income as it is not indicative of our ongoing operating performance.

The tables at the end of this release provide detailed reconciliations of each non-GAAP financial measure we use to the most directly comparable U.S. GAAP financial measure.
